A heatsink structure for solid-state image sensors includes a foil-like heatsink sheet made of a high heat conductivity material. The heatsink sheet has a first fixed portion fixed to a solid-state image sensor and a second fixed portion fixed to another member. The heatsink sheet also has a plurality of cutout portions formed along directions from the first fixed portion toward the second fixed portion. Thus, the heatsink structure can cool the solid-state image sensor while reducing any external-force loads applied to the solid-state image sensor with a relatively simple structure.

In a fluorescent X-ray analysis method, a sample () is set on a sample stage () on an upper side of an X-ray irradiation chamber () and a sample cover () is closed from the upper part of the sample () to surround the sample (), and then, a lower plane of the sample () is irradiated with X-ray for analysis. When the sample () is set on the sample stage () and the sample cover () is closed, a cover detecting means () detects that the sample cover () is closed and X-ray is automatically projected from an X-ray source () to start analysis.

It is possible to solve the problem of the conventional fluorescent X-ray analysis that a concentration calculation result can be obtained only after elapse of a time set as a measurement time. In the fluorescent X-ray analysis method and fluorescent X-ray analysis device according to the present invention, a sample measurement condition is set before starting the measurement and the measurement concentration of the element contained in the sample and the measurement accuracy are calculated. When the measurement accuracy has become a value satisfying the predetermined measurement condition, the measurement is terminated and the concentration at that moment is outputted.

A method of mounting a semiconductor laser component capable of preventing deterioration of laser characteristics and destruction of the semiconductor laser component due to a rise in temperature and a residual stress of the semiconductor laser component. The semiconductor laser component is mounted on a submount by heating and pressure-bonding, and is heated again up to a temperature more than a melting point of a bonding member at the released pressure to release the residual stress.

The concentration(s) of element(s) contained in an unknown sample is measured without necessity of judging the sample relying on a human's eye and obtaining information from a supplier of the sample previously. The concentration(s) of trace element(s) such as Cd, Pb and Hg contained in parts for electronic or electric equipment is determined by (1) irradiating the sample with an X-ray so as to identify whether the type of the sample is a nonmetal-based material or a metal-based material; (2) selecting measuring conditions for a fluorescent X-ray analysis depending on the identified type of the sample; and (3) measuring the concentration(s) of one or more element(s) contained in the sample by the fluorescent X-ray analysis according to the selected measuring conditions.
